Ashes of Creation: JWST Uncovers Silicate Dust in Massive Star Clusters
Daniel Maschmann, Bradley C. Whitmore, David A. Thilker +35
Dust production is a fundamental aspect of the baryonic cycle of star formation. It is known that dust is injected into the interstellar medium during early star formation by super…
Stellar structures, molecular gas, and star formation across the PHANGS sample of nearby galaxies
M. Querejeta, E. Schinnerer, S. Meidt +32
We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct morphological masks of sub-galactic environments based on Spitzer 3.6 micron images. At the…
Origin of the IRAS Vela Shell: New Insights from 3D Dust Mapping
Bore Annie Gao, Catherine Zucker, Tirupati Kumara Sridharan +15
The IRAS Vela Shell (IVS) is a structure of enhanced FIR emission located towards the Gum Nebula, a prominent region of emission in the local Milky Way shaped by various…
Polycyclic Aromatic Hydrocarbon and CO(2-1) Emission at 50-150 pc Scales in 70 Nearby Galaxies
Ryan Chown, Adam K. Leroy, Karin Sandstrom +44
Combining Atacama Large Millimeter/sub-millimeter Array CO(2-1) mapping and JWST near- and mid-infrared imaging, we characterize the relationship between CO(2-1) and polycyclic aro…
Evolutionary growth of molecular clouds as traced by their infrared bright fraction
E. J. Watkins, N. Peretto, A. J. Rigby +3
Understanding how stars form, evolve and impact molecular clouds is key to understanding why star formation is such an inefficient process globally. In this paper, we use the infra…
Do stars still form in molecular gas within CO-dark dwarf galaxies?
David J. Whitworth, Rowan J. Smith, Simon C. O. Glover +6
In the Milky Way and other main-sequence galaxies, stars form exclusively in molecular gas, which is traced by CO emission. However, low metallicity dwarf galaxies are often `CO-da…
